MUSIC-LEAF TURNER. I

SPECIFICATION formingpart of Letters Patent No. 234,676, dated November 23, 1880,

Application filed November 20, 1879.

To all whom it may concern:

Be it known that I, JOHN A. KLINE, of Batavia, in the county of Olermont and State of Ohio, have invented a new and useful Improvement in Music-Leaf Turners, which improvement is fully set forth in the following specification and accompanying drawings,inwhich-- Figure 1 is a front view; Figs. 2, 3, 4, and 5, enlarged cross vertical sectional views of disks for operating the fingers Fig. 6, enlarged view of pivoted handle, and Fig. 7 cross-sectional view of Fig.1 through the line 00.

The object of this invention is to provide a music-leaf turner which is simple in construction and not liable to get out of order.

In the drawings, A represents aseries of vertical strips secured at the upper and lower ends to crosspieces B, forming a frame. A tapering base-piece, O, is attached to the lower edge of this frame, and the whole is then capable of being placed on the music-rest of a musical instrument.

D represents a plate, lapping over the edges .of the two inner or central vertical strips, A.

A shaft, E, is journaled at the lower part of the frame by means of a piece, A, joined to the two inner vertical strips A, and above by means of a strip, B, fastened to the side of the frame. This shaft is coupled at its lower end, by means of a universal joint, F, with a rod, E, which is pivoted in a slotted portion formed in the inclined base-piece O. The shaft E is permitted to move eudwise, and is also capable of being revolved. The upper end projects beyond the frame, and is provided with.a spring, H, and nut H. The shaft has a lug or nib, M, on its surface a short distance from and above the strip B.

The disks I J K on the rod are each provided with slots N, to correspond with the lug on the shaft E. The disks 1, J, and K have rigidly attached to them the arms I J K, at the extreme ends of which are fingers L, that .turn down on the music-frame, the arm 1 of the upper disk being the longest, the arm J next in length, and so on. Thus any number of disks and arms could be placed on the eX- tremity of the shafts E without departing from the spirit of my invention.

A washer, E, is placed on the shaft E above the disk I, and a coiled spring, H, interposed on the shaft between this washer and the nut H, the object of which will hereinafter be more fully set forth.

The tapering base-board O is formed in two parts having an opening betweenwhich a sleeve, F, ispivotedbymeans ofjournalG. TherodE, having on its lower end a knob, passes through this sleeve, and is connected with the vertical shaft E by means of the universal joint F. Any movement of the rod E on pivot G will cause the shaft E to move upward or downward. A strap, 0, on the lower edge of the tapering base-board holds them together rigidly.

O is a horizontal cleat or guard-frame, for supporting the music-sheets placed on the frame. To enable this piece to be vertically adjustable, a strip of metal, P, (shown in Fig. 7 is attached by its ends to the under side of 0, so that it will bind on the two inner vertical strips A of the frame. The piece 0 can then be raised or lowerd to suit the height of the music placed on the frame.

D represents a wire finger, soldered or permanently attached to the journal B, and extending downwardly parallel with and above the shaft E. D is another wire finger, projecting upwardly from the piece 0.

The operation of the apparatus is as follows: The sheet-music is opened and passed under the fingers D D at the line where the sheet folds. The leaves are then all turned to the right of the frame, and the clamps L are shown in dotted lines attached to the upper edge of the leaves, the clamps on the shortest arm K being affixed to the first leaf, the clamp on arm J to the second leaf, and so on.

The position of the shaft E, disks I J K, and arms is shown by Fig. 5 in section, in which the lug M engages the slot N of disk K. The knob on rod E is now turned to the left, which rotates the shaft E and throws the arm K in the position shown in Fig. 4. The slot in the disk then coincides with the slot in disk J, and the spring H, interposed between the washer E" and nut H, draws up the shaft E until the lug M engages the slot in disk J. The apparatus is now in condition to turn the next leaf, which is done by again turning the knob on rod E to the left, as before. This throws the arm J to the left and causes slot N in disk J to coincide with the slot in disk I. The spring H, as before, raises the shaft E, and engages the lug M with slot N in disk I, as shown in Fig. 3. Arm 1 is then in like manner thrown to the left.

In turning the music back the operation is performed in like manner, except that the knob on rod E is turned to the right, and it is only for the purpose of turning the music back that the rod E is pivoted as shown. When the leaf attached to the clamp on arm I is thrown to the right, the position of the lug M and slots N is shown by Fig. 3. The spring H tends to keep the lug M in the slot of disk I, and to draw it down in the corresponding slot of disk J the knob on rod E is slightly raised, and, swinging on its pivot G, draws down the rod until it engages with the slot in disk J, when the purpose set forth.
